Overview
The ICC-HE Head-End Network Controller converts RS-232 protocol for 2-way distribution over RF coax, twisted
pair wiring, and RS-422. The ability to network TVs, video projectors, and large-screen video displays over the
existing CATV coax cable simplifies the creation of large-scale distributed TV control systems by eliminating the
need to run additional control wiring. Employing clear-channel RF frequencies to transmit and receive data, the
iCC-Net network is compatible with most CATV systems without conflict with existing channels. The bi-
directional network operates over a standard low-split cable system, simplifying installation and support.
The iC-Net network can also be distributed as iCW-Net over Category 3/5 wiring or RS-422/RS-232 connections.
Three iCW-Net ports are included, each capable of connecting thousands of ICW-Net format controllers over
wiring runs of up to 3,300 feet (1 Km). In addition, iCW-Net data can be sent to remote locations over RS-422
fiber and RS-232 video conferencing codec data ports.
•Networks with up to 4,000 TVs through wired iCW-Net and broadband CATV iCC-Net networks
oiCC-Net operates through same CATV coax as TV channels, requires no additional wiring
oiCW-Net distributes data over Category 5 or 3 wiring, fiber optic cable, or codecs
•Sends commands to individual devices, zones, or all units from a single RS-232 port
•Interacts with CR ABC Media Retrieval Systems, iC Commander software, or custom control systems
•Includes local control buttons and I/O ports that can trigger events in PC software or control systems
•Provides LED feedback for network, control, and operation status
•Employs new S12-series processing, offering software-upgradeable firmware and improved operation
New Features (3.1)
•New Check RF Levels (AR–page 8) command measures the level of background RF at 5.6MHz,
sends a reply that stated background RF level and current RF sensitivity setting.

Installation
Remote Control Connection
1. Attach appropriate RS-232 cable to Remote Control RS-232 port. See page 4 for RS-232 cable wiring diagram.
2. Set desired baud rate on front-panel DIP switch. Default setting is 19.2K baud – see page 4 for DIP switch setting
information.
RF Coax and iCC-Net Operation
1. Connect an RF coax feed from RF Out to the system’s RF combiner, mixing the iCC-Net Out signal with the other
CATV channels. The iCC-Net Out channel operates at 74.7 MHz, in between cable channels 4 and 5.
2. In most applications, the installer will connect the included 10 dB attenuator in between, trimming the He’s standard
55 dB output to 45 dB.
3. Using an RF signal level meter, use the front panel RF Out adjustment counterclockwise to match the RF Out signal to
the other CATV sources. Limit RF Out adjustment to -10 dB, using attenuators to achieve a lower signal strength.
4. Add a Sub-CATV Diplexer after the CATV amplifier.
5. Connect the Sub-Channel output of the Diplexer to the HE RF In connection.
6. Using a terminal emulator, send an AR command (p8) a few times to measure the level of background RF compared
to the current Sensitivity setting (DIP switch 1, p4).
7. Set one iC-Net controller to constantly transmit using iC ToolKit. Send the AR command again the measure the level
at Constant Transmit.
8. The Sensitivity level should be set in-between the background RF and constant transmit levels.
AC Power and Net LED operation
1. Insert DC power supply plug into the Power In jack.
2. Plug power adaptor into AC wall outlet, the front-panel LEDs should turn on momentarily.
3. If iC-Net communication is functioning, the Net LED will flash once per second, or twice per second (the double-flash,
indicating a difference between present and expected device, would be typical in the initial phase of the installation.)
I/O Port Connection
1. A simple contact closure can be wired to I/O 1 or 2, a press or release can trigger events in the PC or control system
software.
2. In other applications, the I/O ports can act as closure outputs, activating an external power relay, 2x1 video switcher
or other device.
3. You’ll have to choose application – the ports act as either an output or input, not both. See Control Connections on
page 4 for wiring and rating information.

RS-232 Terminal Commands
Employ standard Windows Terminal program, set to baud rate match DIP switch setting on front of HE.
Command Description
Commands shown in ASCII and end with carriage return
(Decimal 13, Hex $0D, or Enter key).
Response displays * character to signify end of characters, or times out if no
characters are received after 2 seconds.
Tip: Just hit Enter to repeat any Terminal command.
Echo Enable EN Enables character echo so you can see typed characters on screen.
Echo Disable EF Disables terminal character display (default).
Version VE
ID Displays HE software version.
Reset Z! Performs system reset.
Show Devices
SD Displays list of 2-way devices stored in HE memory. List can be created by iC
Commander software, ABC-MRC software, or Scan and Build command below.
Example Response: Devs Present:
257-261
263
265-271*
Show Missing SM Displays list of missing 2-way devices (compared to HE memory list).
Example Response: Devs Missing:
262 -263
264*
Show Present SP Displays number of present devices and number of devices expected.
Example Response: Num Devs Present : 1
Num Devs Expected : 53
Scan and Show SZ Scans iC-Net and displays list of all 2-way devices found (does not change HE
memory).
Scan and Build Z^ Scans iC-Net and saves list of all 2-way devices found into HE memory.
Show Log L Returns four hex bytes, separated by commas. If any of the bytes change as you
repeat the command, there is likely an error in return communication from iC-Net
devices.
Clear Log DL Clears the L hex bytes to zero.
Check RF
Receive Level AR Level RF Received (idle)
Example Responses:
AR RRRR/SSSS = Receive/Sensitivity levels
AR 0321/1337 = 0.321V “quiet” receive level, 1.337V high threshhold
AR 0321/0693 = 0.321V “quiet” receive level, 0.693V low threshold
AR 2250/0693 = 2.251V constant transmit receive level, 0.693V low threshold
This command is used to check RF levels at 5.6MHz, compared to the current
sensitivity level setting (DIP Switch 1, page 4). Test the RF receive level a few times
when the iC-Net units are not transmitting, then again when one iC-Net unit is set to
constantly transmit. The Sensitivity level should fall about halfway between quiet
and constant transmit RF levels.

RS-232 Control Protocol
Overview
RS-232 control for up to 4000 iC-Net devices is provided through an iC series Head-End Network Controller. The
ICC-HE Head-End manages iC-Net communication over RF Coax to ICC-series devices as well as ICW-series
devices over twisted-pair Cat3/5 wiring. The ICW-HE Head-End operates on the Cat5 network only.
Each device is assigned a unique device number from 1 to 4000 to which control commands are addressed. The
devices are organized into 16 zones of 255 devices. All the devices in each zone will respond to a single “virtual
device number” — one device number that represents all devices in each zone. There is also a global device
number, 4095, that will command all devices in the system. This feature dramatically speeds up system
operation and programming, because one command can affect an entire group of devices—or all. To take
advantages of this feature, review the section iC-Net Zones in this manual.
In ABC Media Retrieval Systems, we reserve the first group of devices, 1-255, for components operating on a
connected control system. Zones 1-16 are used for CR TV Controllers, Video Display Controllers and Tuners. As
it’s unlikely any system will use all 4000 devices, this may be a good device standard for your system as well.
The Remote RS-232 port on the Head-End Network Controller can communicate from 1200 to 38.4K baud. The
factory default setting is 19.2K baud, 8 data bits, No parity, and 1 stop bit.
Command String Structure
Characters in command strings are expressed
in a combination of hex and ASCII characters.
•Single-byte hex numbers are preceded
by the ‘$’ symbol
•ASCII characters or strings are
enclosed in single quotes
•Numbers not marked as hex or ASCII
are a single decimal byte
•Parameters shown in < > brackets are
single byte
•A series of multiple commands or
parameters are set apart by [ ]
brackets
•Commas separate the bytes, but are
not part of the protocol
•Double quotes enclose the command
string, but are not part of the protocol
Command format
“$A5,<dh>,<dl>,<ncb>,<cmd1>,<parameter> [<cmdN>]"
$A5 Starts the command
<dh> The zone or high order byte of the device
<dl> The unit or low order byte of the device (0
for global zone)
<ncb> The number of command bytes to follow
<cmd1> The first command byte
<parameter> Command parameters (not used by all
commands)
[<cmdN>] Multiple commands can be concatenated,
with byte count added to <ncb>
